usb: gadget: fastboot: detach usb just before rebooting
The patch fixes the following error when updating a BSH SMM S2 board:
3:72>Start Cmd:FB[-t 8000]: ucmd nand write ${loadaddr} nanddtb ${filesize}
3:72>Okay (0.023s)
3:72>Start Cmd:FB: reboot
3:72>Fail Bulk(R):LIBUSB_ERROR_IO(0s)
The "fastboot reboot" command detaches the USB when it still needs to be
used. So let's detach the USB just before the reset.
